i i i WINDOW CONSTRUCTION. Y

Application 1ed April 13, 1922. Serial No. 552,260.

To all whom t may Concern:

Be it known that I, CHARLES A. KARPEN- STEIN, a citizen ofthe United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Window' Constructions, of whichthe following is a full, clear, and exact description.

lNIyinventionV relates to improvements in window constructions, and it consists in the combinations, Constructions, and arrangements herein described and claimed.

An object Vofmy invention isto provide a window construction in Vwhich the movable sash is prevented Y from any lateral play, thereby obviating the rattle which is customary from the Ordinary window.v

A further object of my invention is to provide a device of the character described in which the movable sash is pivotally mounted, whereby the sash may be readily swung into any desired position.

A further object of my invention is to provide a device of the character` described in which the sash is frictionally held inadjusted position.

A further object of my invention is to provide a device of the character described which provides an air-tight connection between the window frame guide-ways and the sash.

Other objects and advantages willvappear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claim.

My invention is illustrated in the accompanying drawings, forming part of this application, in which v Figure 1 is a front elevation rof the device, portions-thereof being shown 1n section, Y

Figure'2 is a section along the line 2-2 of Figure 1,

Figure 3 is a perspective view of a por tion of the device, and

Figure 4 is a section along the line 4 4 of Figure 1.

In carrying out my invention, I make use of the ordinary window frame 1 which has a weight receiving compartment 2 therein. A window sash 3 is mountedv in the window frame 1 and is provided with V- shaped groove sides 4, these sides being lined with a metal plate 5. A guide member 6 is slidably disposed in a groove 7 in the frame 1 andV has a V-shaped portion 8 which 110 with a friction ,plate'or slice 11.

V is snugly received within the groove 4.1 'Ihe .guide 6 is connected to the plate 5'by `means of'a pivot pin 9 (see Figure From this construction itl will be apparent that, the sash 3 may be swung.about thepivot 9 and will moverthe guideinwardly to the dotted;

line position-shown in Figure 4. Y

The guide Gis connectedby means of links *n shoe is vadaptedto engage with the.A inner wall of the groove '7 and thereby holds theA sash 3 against movement. The ordinary window weight 12 is connected by means 'of' a chain 13 to the upper link 10 (see Figure 3). The chain 13 is passed overan idlerV pulley 14 which is carried by the frame 1. It is obvious that theweight12 tends to swing the links 10 upwardly about their pivots 15 so as to throw the shoe 11 into engagement with the frame 1. The other side of the window sash 3 is provided with the guide member 6v and the shoe 11 in the same manner as heretofore described.V

From the .foregoing description of the various parts of the device, the operation thereof may be readily understood.V VIt isl obvious that the window sash 3 may be raised or lowered in the ordinary manner, and it will be supported in adiusted positionv by means of the weight- 12. The weight 12, however, is not connected to the window sash 3 in the ordinary manner, but as heretoforeV stated, is connected to the upper linkIO.

Vwhereby vthe weight of the member 12 will cause the shoe 11 to engage with the frame 1 and prevent the window Vsash 3 from lateral-movement as well as upward movement. VThe weight 12 furthermore acts as a yielding means'which permits theguide This member 6 to move inwardly toward the shoe 11. As heretofore stated, the guide member 6 is moved laterally when the winl dow sash 3 is Vswung about the pivots 9.

The sash 3 carries aV sleeve 9 that slidably Y receives the pin 9. In Figure 4, I have shown the window sash 3 swung intoV the dotted line posit-ion, and have shown the member 6 moved inwardly so that the vertex,` of the member 6 is disposed Substantially flush with the'inner side of the frame 1. The y window sash 3 can be lowered in the ordinary manner, and will cause' the shoe 11! to move downwardly therewith. By pivot-- ing the window sash 3 to the guide member 6, I providea novel means'bywhich the inner and outer sides of the window may be readily-.1Wigsliedwithoutitlie necessity off ztV Lela-imi l persen Standingffn'the f'eutside-iof the Win- In al windew leonstruetionyasesh having` dow.
